Whatsminer M31S — Stable, Efficient, and Proven SHA-256 Miner

The Whatsminer M31S from MicroBT delivers dependable performance for long-term Bitcoin mining. With a hashrate of 76 TH/s and power consumption around 3,312 W, it achieves an energy efficiency of approximately 43.6 J/TH. Compared with other miners in this range, the M31S offers a smoother balance between power draw, noise level, and reliability — a reason it remains popular in both small and mid-size farms across the UAE and GCC.

At AryaMiner, we provide both brand-new and tested used units. Each used unit is professionally inspected, cleaned, and benchmarked by our technicians before shipment. This ensures that every miner reaches its rated hashrate. Buyers can choose between new units backed by manufacturer warranty or cost-effective tested ones for faster ROI — a major advantage compared to most listings on generic reseller sites.
